Tech Tip: Overriding the C compiler with ExtUtils::MakeMaker

By Shlomi Fish on September 9, 2012 1:34 PM

In order to override the C compiler with ExtUtils::MakeMaker, one can do something like:

perl Makefile.PL CC=/usr/bin/clang

Which will make the "CC" variable in the generated makefile be set to /usr/bin/clang instead of the default. Apparently, setting the CC environment variable does not work like it does with CMake.

Thanks to Sisyphus for the tip.

If you want to permanently use this setting put it in the $ENV{PERL_MM_OPT}. Module::Build has also its own $ENV{PERL_MB_OPT}.

This feature is used in particular by local::lib to change the install directory for CPAN modules.
